Winds gusting near 50 miles per hour or more toppled trees and PG&E power lines across Interstate 80, near Redwood in Vallejo, shutting down the entire freeway in both directions during the afternoon commute while PG&E crews turned off electricity to the downed wires and firefighters put out a small fire sparked by the damage.

Nine people were injured, three critically after a big rig careened through the center divide on Interstate 880 in San Leandro, crashing into on-coming traffic and triggering a chain reaction of additional crashes in the aftermath.
